Application filed August 8, 1904. Serial No. 219,886.

To all whom it nanny concern.-

Be it known that Vl ILLI1UIADOLTIITQMVE- MAN, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have inventeda new and useful Improvement in GasddurningConvertible I-leat ing and Cooking Stoves, of which the follow ing is aspecification.

My object is to provide a gas-stove of a par ticularly simple,inexpensive, and desirable construction which may be used convertiblyfor heating and cooking purposes.

In the accompanying drawing T show a vertical section of a stove of oneconvenient and attractive form embodying my improvements.

Mounted upon an ornamental base A is a hollow pipe or pillar B, upon theupper end of which is a hollow expanded head C, having a closed top a.In the side of the head or burner just below the top is an annularseries of perforations or burner-openings b. At the lower end of thepillar is a spider 0, having a central opening surrounded by air-inletopenings.

1) is a U-shaped gas-pipe provided with a cock (Z near one end and a tipa at its other end. One leg of the pipe passes through an opening f inthe base, while the other leg passes through the central opening of thespider to position the tip or outlet e centrally in thelower part of thepillar. The pipe may be raised and lowered in the opening f and fastenedin adjusted position by means of a thumbscrew 0. The outer end of thepipe D may be connected with a hose or the like l), leading thereto froma gas-supplier, and the stove is adapted to rest at its base on thefloor. "vi'hen the cock (Z is opened, gas passes from the tip 0 to theair and mixing chamber, formed by the hollow pillar and bu rner-head,air to mix with the gas entering through the openings at the lower endof the pillar. The burning mixture passes out through the burneropenings.7), where it ignited. To facilitate thorough mixing of the gas and airbefore they pass to the openings 7), I prefer to provide a line-meshscreen A in the top of the pillar and another, 1', in the burner-headbeneath the burneropenings.

Surrounding the pillar B is a sleeve 71:, suptened, when adjusted, bymeans of the thumbscrew 1.

F is a preferably frusto conical hollow metal hood or deflector providedat its base with a recess m to lit over and rest upon the top a of theburner-head. The hood. F has a top plate a, and fitting upon the hood inthe manner shown is an ornamental stove-top The mixture of air and gasburns at the openings Y) with a blue flame free from odor, indieatingapproximately perfect combustion. When the hood is in place, the flameplays against its under surface to heat the same and the products ofcombustion are deflected by the exposed frusto-conical surface in thedownward and outward directions, resulting in the most perfectheat-radiation for warming a room.

Constructed as described my improved stove may be readily moved fromplace to place and quickly converted into a cooking or heating stove, asdesired.

The platform E may be raised to a plane above the burner-head when thedeflectinghood is removed and the stove is to be used for cooking andthe cooking utensils may be placed thereon. When the platform is lowered to a plane below the bUl11GI-O1')G1ll11g8 with the deflecting-hoodeither in place or removed, it may operate as a support for bread whiletoasting or when at a lower level as a support for dishes to be warmed,etc. Obviously it is imn'iaterial whether the platform is adjustablerelative to the burner-openings, as shown, or the burner is adjustablerelative to the platform for bringing the openings above or below thelatter.

The stove constructed with the pipe or pillar ll as the sole support forthe upper parts has a particularly unique and attractive appearance. Ifdesired, however, the stove may be constructed with a frame of anysuitable form to support the burner, the top, and the ad justableplatform or all those parts, and in other ways theconstruction may bevariously IOO holder adjustably supported on said pillar to adapt it tobe raised for cooking purposes above the plane of the burner-openings,and to be lowered below the plane of said openings to expose it to thedownwardly-deflected heat from said deflector, substantially asdescribed.

forming the mixing-chamber and terminating in a burner-head havingopenings, With gaseous-fuel-supplying means and an air-inlet in thelower part of said pillar, a heat-deflector surmounting said head, and acooking-utensil WILLIAM AI) OLPH KQNEMAN.
